Alastor



Alastor is a living Devil Arm, the "Thunder Sword" and "Spirit of Lightning", appearing in Devil May Cry. It is also one of the two keys alongside Ifrit that can unlock Dante's inner, unlimited power. It can only be wielded by the "chosen one" who can conquer it, but it is able to grant its possessor lightning speed and aerial capability.

Gameplay
While the Alastor is equipped, the menu screens are shrouded in lightning

Alastor the Thunder Devil
Dante finds Alastor impaled through the chest of a sculpture of an agonized woman, and it speaks to Dante of its intent to enslave him. It flies through the air and nails him to the ground, but he removes and subdues it, becoming one with it in the process.

After that point, Dante can use Devil Trigger and channel Alastor's power, enhancing his attacks with lightning and allowing him to take the form of a winged, tailed Demon.

Viewtiful Joe
Alastor's manifested spirit, Blade Master Alastor, appears as a recurring boss and sometimes as a playable character in the Viewtiful Joe series, also by Capcom. It is revealed in Dante's story line of the game that Alastor has left the sword due to Dante's carelessness. Dante responds by saying Alastor "really knows how to hold a grudge." Also, Dante wields the Alastor during his appearances in Viewtiful Joe and Viewtiful Joe: Red Hot Rumble.

Sengoku Basara
Alastor also appears as one of the final weapons for Date Masamune in Sengoku Basara 2 (Azure Dragon in Devil Kings), and there are six copies of Alastor that Date Masamune can use. When you first acquire Alastor with Azure Dragon, it is actually called "Azure Prophet".

Background
Alastor, meaning "Avenger", was a genius of familial feuds in classical mythology, and encouraged violent retribution. In this respect, it often referred to Zeus, the lightning god. In Christian demonology, it became the chief executioner of Hell.

Trivia

 * One of the hosts of the series Mythbusters, Jamie Hyneman, has a prop version of the Alastor which can be seen in his office. This is because his visual effects company, M5 Industries, was behind the US Devil May Cry commercial
 * The Thunder Edge of Okami, wielded by Amaterasu, is a similar lightning sword whose Sub-Glaive lunge attack is very similar to the Alastor's Stinger attack.
 * In the In-game Devil May Cry weapon file, It says Alastor grants the user "Lightening speed". The reason for this error is unknown.
